比较状语从句讲解及精选练习(附答案)
比较状语从句比较状语从句表达人或事物的属性或特征的不同程度。
主要运用于形容词和副词的原级、比较级及最高级的句子之中。
原级：as…as（和……一样），not so（as）…as …（和不一样）；比较级：more…than（更）；最高级：The most…in/of，the + 形容词+est…of/in。
一．原级比较1.as+原级+as（第一个as是副词，含“如此”的意思，在主句说明所比内容的程度；第二个as是连词，含“比”或“如此”的意思，引导从句）。
例如：Our classroom is as big as theirs. 我们的课室跟他们的一样大。
I hope you like it as much as I do. 我喜欢你跟我一样喜欢它。
在这种结构中，比较成分的前面常用表示倍数的词如···times（···倍），twice（两倍）等来表示相比较的两个成分相差的倍数，通常译作“像···几倍那样多”，“是···的几倍”。
例如：The speed of sounds in water is about four times as great as in air.声音在水中的速度是空气中的4倍左右。
This book is twice as thin as that one. 这本书的厚度是那本书的二分之一。
2.not so / as ···as（不像···那样，不如）。
第一个as/so是副词，在主句中作状语，修饰其后的形容词/副词；第二个as是连词，引导从句。
not so…as比not as…as用得比较普遍。
例如：It is not as easy as you think. 事情并不像你想的那么容易。
The work did not go so smoothly as we hoped. 这工作并不像我们希望的那样顺利。

比较状语从句比较状语从句表达人或事物的属性或特征的不同程度。
主要运用于形容词和副词的原级、比较级及最高级的句子之中。
原级：as…as（和……一样），not so（as）…as …（和不一样）；比较级：more…than（更）；最高级：The most…in/of，the + 形容词+est…of/in。
一．原级比较1.as+原级+as（第一个as是副词，含“如此”的意思，在主句说明所比内容的程度；第二个as是连词，含“比”或“如此”的意思，引导从句）。
例如：Our classroom is as big as theirs. 我们的课室跟他们的一样大。
I hope you like it as much as I do. 我喜欢你跟我一样喜欢它。
在这种结构中，比较成分的前面常用表示倍数的词如···times（···倍），twice（两倍）等来表示相比较的两个成分相差的倍数，通常译作“像···几倍那样多”，“是···的几倍”。
例如：The speed of sounds in water is about four times as great as in air.声音在水中的速度是空气中的4倍左右。
This book is twice as thin as that one. 这本书的厚度是那本书的二分之一。
2.not so / as ···as（不像···那样，不如）。
第一个as/so是副词，在主句中作状语，修饰其后的形容词/副词；第二个as是连词，引导从句。
not so…as比not as…as用得比较普遍。
例如：:It is not as easy as you think. 事情并不像你想的那么容易。
The work did not go so smoothly as we hoped. 这工作并不像我们希望的那样顺利。
二．比较级1. 形容词/副词的比较级+than+被比较的对象。
表示两个人或事物在某（些）方面的差别。
than是连词，引导从句。
后面被比较对象如果是名词，多用省略形式，省去与主句中相同的部分。
Man grows fast er than the planet he inhabits. 人类成长的速度远比他居住的星球快得多。
注意：① 从句中的主语（名词）如果与主句中的主语一致，为了避免重复，常用that代替不可数或某可数名词，用those代替可数复数名词，用one或ones代替可数名词。
例如：The result of this experiment is better than that of the last one. 这次实验的结果要比上次好。
The students in our class are more diligent than those in their class. 我们班的学生比他们班的学生用功。
② 比较状语从句的动词，如果与主句的谓语动词一致，且为行为动词时，常用do（does，did）代替，以免重复。
例如：~We have produced even more coal this year than we did that year. 我们今年出产煤要比去年出产得更多。
She drives better than her husband does. 她开车开得比她丈夫好。
2.① “no+比较级+than”（不比···多，不少于）。
no是副词，在主句中作状语，修饰形容词或副词的比较级；than是连词，引导从句。
例如：Tom is no less diligent than peter. 汤姆用功不比彼得差。
（汤姆和彼得同样用功）He feels no better today than he did yesterday.他今天的感觉不比昨天好/他今天的感觉跟昨天同样不好。
② “ not more than” 不如… (前者不如后者)Jack is not more diligent than John. 杰克不如约翰勤奋。
3．句型the···the···（越···越···）。
即：从句：the + 比较级···，主句：the + 比较级···The more we study, the more we discover our ignorance. 我们越学习，就越发现自己无知。
主句如果是将来时，从句可用现在时代替将来时。
例如：，The longer the treatment is delayed, the worse the prognosis will be. 延误治疗的时间越长，预后越差。
三．最高级1. The most…in/ofThis book is the most interesting of the three. 这本书是三本中最有趣的。
2. the + 形容词+est…of/inThis road is the busiest street in our city. 这条路是我们城市最繁忙的街道。
3. one of the + 名词(复数)….之一(用于最高级)Tom is one of the best students in our school. Tom是我们学校最好的学生之一。
